Geforce GTX 680 Mac Edition

Has anyone got any experience with this card yet. It's quite new and I am keen to have a card that still gives me access to the boot screen in OSX. I am only planning to be using it to grade 1080 rushes and it would be a sole card.

Yup sounds like the card for you then! Unless you render beyond 1080 ever...then you should get the 4GB version which wont have the boot screen BUT especially in Resolve10 will be important to have that extra RAM on the card...i suggest you 'future proof' your box by getting the 4GB if you don't mind losing boot screen.
